Storm front and dormouse day: weather warnings for Hesse!
What awaits us in Cologne next week? According to current weather warnings, there will be an interesting weather situation influenced by a storm over Scandinavia. The first warnings of wind and gusts of wind have already appeared in Hesse, and similar conditions could also apply to the local region. The hot summer that has been getting under our skin in the last few days is giving way to an approaching change in the weather. This is what our colleagues report HNA that temperatures could well exceed 30 degrees in the coming week.
Thunderstorms, hail and heavy rain are expected for Monday, June 23rd, especially in northern Hesse. But not only that, Thursday night also promises a lot of excitement, as heavy thunderstorms and showers are forecast. But with all these meteorological capers we also have a very special date coming up: Dormouse Day on June 27th.
Peasant rule with history
Dormouse Day has a special meaning that goes back a long way. An old farmer's rule says: "If it rains on Dormouse Day, the rain may not subside for seven weeks." This rule, which has been with us for generations, suggests that the weather conditions on that day have a direct influence on the Saxon midsummer period, as do the ladies of goFeminine report.
The origin of the name goes back to seven brothers who fled to a cave near Ephesus during the persecution of Christians in 251 AD. They were trapped there and only woke up again in 446 AD. This story would give the holiday its name and keep it alive. However, whether the rule is scientifically tenable remains an exciting topic, as historians and meteorologists continually discuss.
What does science say?
People have used various signs of nature to predict the weather for centuries. In the Middle Ages, the so-called peasant rules emerged, which come in a rhymed form. These traditions are part of the rich meteorological knowledge that has continued to develop since modern times. Current scientific findings show that cloud shapes and densities are important indicators of upcoming weather developments. Certain clouds indicate rain or stable weather, while others, such as cumulonimbus clouds, can even signal severe weather, as the contributions show Planet knowledge explain.
Today, modern technologies help us forecast weather data with up to 90 percent accuracy for a week in advance. This is a completely different approach than the well-known farming rules - but still very exciting! Perhaps Dormouse Day will bring us a touch of nostalgia in this regard as we continue to trust the forecasts of meteorologists.
So, dear Cologne residents, keep an eye out for the weather report! As we prepare for Dormouse Day, it will be interesting to see whether the old farmer's rule holds true or whether we can expect a bright, sunny midsummer.
